does anyone know the open 600 gear (08 Yamaha) and the restricted gear (05 Yamaha) for Plaza Park in Visalia

I've heard 12-51 for the Yamaha.  Not sure about the restricted.

We ran a 12/50 last year cause the 51 was turnin way to much and got the motor hot. But that was an 05 yamaha. the 08 will be different.
